NASA observed the once-hurricane Aletta intensify, now weakening quickly

When Tropical Storm Aletta intensified and became a hurricane in the eastern Pacific Ocean the Global Precipitation Measurement mission or GPM core satellite passed overhead to analyze the major hurricane's rainfall rates. Over the weekend of June 9 and 10, however, Aletta ran into adverse conditions and weakened quickly. Aletta was a powerful hurricane with winds of about 85 knots (98 mph) when the GPM…

A better device for measuring electromagnetic radiation

CAMBRIDGE, Mass. - Bolometers, devices that monitor electromagnetic radiation through heating of an absorbing material, are used by astronomers and homeowners alike. But most such devices have limited bandwidth and must be operated at ultralow temperatures. Now, researchers say they've found a ultrafast yet highly sensitive alternative that can work at room temperature -- and may be much less expensive. The findings, published today in…

Discovery in the sky with nanodiamonds

A faint and mysterious stream of microwaves emanating from star systems far out in the Milky Way could be caused by tiny diamonds, new research has suggested. For decades scientists have been able to measure this 'glow' of microwave light, dubbed the anomalous microwave emission (AME), coming from a number of regions in the night sky, but have yet to identify its exact source. In…

The Hubble Space Telescope discovers the most distant star ever observed

If we could travel halfway across the Universe, we would find a huge star,christened Icarus, that was found after its discovery to be the most distant star from Earth. Normally, it would be impossible to detect it, even using the most powerful telescopes currently available, were it not for a quirk of nature that had amplified its brightness such that it could be detected with…
